Do you mean how stable? I use 1.4.1_01 and have had no problems with it what-so-ever. Well, no problems related to the JDK or JRE. I create all my own kinds of problems though. BTW - I have used it on Windows XP, SUSE 7.3, Mandrake 8/9

hi, We are facing lotof problems in jdk1.4. This is not full compatable with jdk1.3 foucus is big problem..and swing memory.. in jdk1.3 70 mb heap but in jdk1.4 ->> 90 mb I am sure jdk1.4 is not stable..

How is 1.4 not compatible with 1.3? All JDK versions are backwards compatible. You may run into deprications of classes or methods, but that is not a bug per say. Also, memory usage is not nessacarily a bug either. There is a lot more SWING in 1.4 than 1.3, so I would expect memory usage to increase a little. 1.4 has no more bugs than 1.3 had/has. I think 1.3 is on release 6 now? I don't see anything significantly wrong with 1.4 to not use it. Especially with some of the new API's offered in 1.4.

We too are facing some compatability issues with JRE1.4.1. Our earlier application was in JRE1.3 and on porting it to the latest version we found that Tab was not working in any of the JApplets! Also certain radio-button/JTableHeader text was also being converted into something like "MyText..." (not enough width for the component it seems). Some other issues were also there.

I suppose, some of the compatibility problems are due to bug fixes. even if this sounds strange. a look into the bugparade might shed some light on such mysteries. if there is no entry for the problem you are facing you should write a test case that shows the different behaviour between the jdk versions. even if they answer that this is no bug they often write some information on what and why it is happening. chantal [ December 02, 2002: Message edited by: Chantal Ackermann ]
